Adafruit and Digi-Key have teamed up to present All the Internet of Things – a six-part video series covering everything you could ever want to know about the Internet of Things.

For our second video, we’ll go over the most popular protocols used in the IoT industry, as well as the upsides and downsides of each type of protocol to help you decide what you’ll use to connect your devices to the internet and exchange data.

A protocol can be thought of as the language each machine, or machines, use to talk to each other. Protocols don’t deal with the messy business of moving bits to and from, they are a higher level set of rules the machines use to talk to each other.
